Title: Electronically controlled fuel injection method of internal-combustion engine
Inventor: KOBAYASHI NOBUYUKI
IPC: F02D41/04
Filed: 1982-03-02
Abstract: PURPOSE:To accurately correct fuel at applicable operation, by performing new correction with a residual value of a fuel correction quantity already under execution as the initial value when acceleration increase and deceleration decrease are duplicated in the method of suitably correcting the basic injection quantity in accordance with an engine operational condition. CONSTITUTION:In a digital control circuit 54, an injection 30 is controlled by reading the basic injection timing from an ROM by intake pipe pressure from an intake pipe pressure sensor 23 and engine speed from a crank angle sensor 44. Here at acceleration, a correction coefficient is increased, and then injection is decreased to a prescribed deceleration speed 0 at each engine speed to perform acceleration increase. While at deceleration, the correction coefficient is minimized, and then injection is restored to a prescribed restoration speed at each engine speed to perform deceleration decrease. When the acceleration increase and the deceleration decrease are duplicated, the deceleration decrease or acceleration increase is performed with a residual value of the acceleration increase or deceleration decrease already under execution as the initial value.

A weak acidity mixture solution of Nb and Ta is introduced into the column to make the mixture material of Nb and Ta adsorbed onto the IEF-SA. Then a mixture solution of sulfuric acid and fluoric acid as a separating liquid is introduced into the IEF-SA to preferentially elute Nb. Then the IEF-SA after eluting Nb is treated, for example, burnt at high temp. to obtain Ta. By this method, the rate of ion exchange reaction and the flowing rate of liquids can be raised.

Abstract: PROBLEM TO BE SOLVED: To achieve a whole-number, high-speed automatic inspection on the in-line system by making high-speed simultaneous measurement of eccentricity, inclination, and warp of an object to be measured having a diffraction lattice in the concentrical form. SOLUTION: A laser beam emitted from a semiconductor laser 11 is, using a beam splitter 13, cast perpendicularly onto a track (concentrical diffraction lattice) located a prescribed distance apart from the rotational center of an optical disc (object to be measured) 30. The laser beam incident on the track is split into the regularly reflected 0-th 0-th order diffraction light conforming the law of reflection and a number of higher order diffracted beams of light based upon the principle of diffraction. The 0-th order diffraction light passes the beam splitter 13 and is received by the first PSD 15 for sensing the two-dimensional positioning. The first order diffraction light is reflected upward aslant and received by the second PSD.  On the basis of the output of the first PSD 15, the amounts of inclination and warp (surface deflection) of the object are calculated from the amount of angular displacement, while the dislocation of the rotational center of the object from the center of the track (eccentricity) is calculated on the basis of the difference between the output of the second PSD 17 and the output of the first PSD 15.

Filed: 1987-02-17
Abstract: PURPOSE:To keep the wall surface temperature of a lamp constant by operating a cooling airflow rate adjusting member for the lamp in accordance with a moving member when a part of this member is moved to change the flow passage constitution. CONSTITUTION:Since an airflow control plate 62, partitioning pieces 64 near the intake part of a lamp cooling fan 10 are close to increase the resistance to air intake and the increase of the flow rate is prevented to prevent the lamp wall surface from being too cooled when a lens attaching plate 61 approaches a lamp 4. When the lens attaching plate 61 is moved in the direction of an arrow (c) away from the lamp 4, the gap between this plate 61 and a spherical mirror attaching plate 60 is extended to reduce the flow rate per unit area in the vicinity of the lamp 4, but partitioning pieces 64 of the control plate 62 are sparse to reduce the resistance to air intake for lamp cooling and the reduction of the flow rate is prevented to prevent the lamp wall surface from being too warmed. Thus, the variance of the flow rate of cooling air to the lamp 4 is prevented when the flow passage is widened or narrowed.
